Top Picks
24" 201cc Electric Start CVT High-Wheel Mower
A premium walkβbehind mower with a 201cc engine, electric start, and CVT drive that adapts to the user's pace. It excels on larger yards and challenging terrain, though the higher weight and price reflect its more robust design.
Overview
This Yardmax 24" mower takes a step up in capability with a 201cc OHV engine, electric start, and a continuously variable transmission (CVT) that offers six speed settings. It's intended for homeowners who want professionalβgrade convenience and control.
Why it stands out
The CVT is particularly useful on varied terrain: it prevents the mower from bogging in thicker patches and allows the operator to set a comfortable walking rate. The electric start is a tangible convenience for those who dislike pull cords.
Considerations before buying
This model is heavier and more costly, reflecting its more substantial engine and deck. Buyers should plan for adequate storage space and be comfortable with its weight when lifting into a trailer or tight shed. For large yards and frequent, demanding mowing, its durability and features justify the premium.

20" 141cc Self-Propelled Push Mower
A lightweight 20βinch mower with a 141cc 4βstroke engine suited for small to medium yards. It starts easy and is simple to store, but build quality and ambiguous height specs may concern buyers with rough terrain.

Itβs lightweight, easy to start, and offers dependable Briggs & Stratton power in a compact package. Itβs best for suburban lots, tight corners, and people who want a reliable, fuss-free mower without paying for unnecessary heft.
FAQ
For most homeowners it is. A self-propelled system reduces fatigue and keeps pace steady, which matters on bigger lawns, slopes, or when grass is thick. If the yard is tiny and flat, a simple push mower saves money and storage space.
Pick a 24" deck to cut more grass per pass on large yards (faster work). A 21"β22" deck is nimbler for yards with obstacles, tight corners, or narrow gates. Bigger decks are slightly heavier and may be harder to maneuver in cramped spaces.
CVT (continuously variable transmission) automatically matches the mowerβs speed to the operatorβs walking pace. That reduces pushback and strain on the operator and drivetrain, especially on slopes and rough terrain. Itβs a premium convenience on stronger models like the 24" 201cc CVT mower.
Basic maintenance every season: change the oil, clean or replace the air filter, sharpen or replace the blade, and check the spark plug. Inspect belts, cables, and the drive system annually. Frequent use or dusty conditions may require more frequent attention.
Mulching returns clippings as nutrients and keeps the lawn tidy without bags. Bagging is best for tall, wet grass or if clippings need to be removed. Side-discharge is simplest for heavy growth when clogging is a concern. Pick based on grass length, local yard rules, and a preference for lawn appearance.
Run the tank dry or add a fuel stabilizer before long storage. Change the oil and clean the deck to prevent corrosion. Store in a dry, covered spot and remove the battery (or keep the electric-start battery on a tender) for winter. Remove the blade or secure it safely for maintenance.
Yes. Self-propelled mowers help on gentle slopes, but steep inclines still require caution. The heavier 24" high-wheel model handles uneven terrain better due to larger wheels and stronger drive. On very steep terrain, a riding mower, string trimmer, or professional service is safer.
Look past low price alone. Check engine brand (Briggs & Stratton is a reliable sign), build materials (steel deck vs. mostly plastic), and drive system quality. A slightly pricier mower with a proven engine and solid drive will often cost less over time than a cheaper model that needs repairs.

Quick question: is electric start worth the added cost and weight? Thinking of the 24″ electric start vs the 141cc 20″ foldable model for convenience.
Electric start minimizes hassle, especially for those who dislike pull cords or have mobility concerns. If your yard is small and storage is tight, the foldable 20″ might be better despite manual start.
If you only mow a tiny yard once a week, I’d pick the lighter 20″ β saves space and is cheaper. But if you have slopes or dense grass, electric start with a bigger engine is worth it.
Long post because I wanted to be thorough:
I purchased the 21-Inch 3-in-1 with the 170cc engine. First few mows were great, cut clean and handled bumps well. Then about 6 months in I had a wheel wobble and one of the plastics cracked where the catcher attaches. Customer service was slow and the replacement part took weeks.
If you’re buying one of the mid-range 170cc models, be prepared for decent performance out of the box but maybe some QC issues later. Still cheaper than a pro-grade mower, but set aside time/parts budget for small repairs.
Good ideas β I ended up using a local shop too and it was way faster. Cost me about $45 for labor and parts vs months waiting.
You might try a local small engine shop β they often have quicker turnaround for parts and repairs than online sellers.
Sorry to hear that, Ethan. Those 170cc models do offer good power but, as you noted, some buyers report plastic parts failing. Keeping a basic hardware kit and checking fasteners quarterly can help avoid surprises.
Same here β had a cracked bracket after one season. I reinforced it with a metal plate and it’s been fine since. Not ideal but cheaper than waiting for OEM parts.
Mixed feelings. I like that many of these mowers are affordable and powerful (170cc looks tempting), but the recurring theme of plastic components and shipping damage worries me. Any maintenance tips to extend lifespan?
Totally valid concern. Regular maintenance: change oil as recommended, clean/replace air filter, check/replace spark plug annually, tighten fasteners, and inspect plastic parts for cracks. Also consider pre-delivery inspection if buying online β record unboxing in case you need a claim.
I keep an extra set of belts and a spare blade. Saved me once when the drive belt frayed β had me back mowing in a morning instead of waiting for parts.
I bought the 24 in. 201cc Electric Start Select PACE model last spring and it’s a beast. Electric start is pure luxury compared to pull-starts, and the CVT really makes mowing big slopes less of a workout.
Only downside: it’s heavier than my old mower so I needed a ramp to get it into the shed. But overall worth the higher price for the performance.
Thanks for sharing, Mark β glad the CVT made a difference for you. If you have a steep slope, make sure to regularly check belt tension; CVT systems can slip if the belt wears.
Good tip about the ramp β I built a small plywood ramp and it made life so much easier. Also: a trick I learned is to keep gas stabilized if you store it over winter.
How’s the mulching on that model? I’m tired of bagging and my yard gets patchy if clippings sit.
I’m torn between the PowerSmart 21-Inch and the PowerSmart 22-Inch. Practically the same price where I live. Does the 22″ noticeably handle thicker grass better, or is it just marketing?
Both are similar in build; the 22″ paired with the 150cc B&S tends to give a bit more torque for thicker grass. If your lawn is mostly normal turf, the 21″ is probably sufficient and a touch easier to maneuver.
I have the 22″ β the extra inch does help a bit on wider swaths, and the 150cc engine felt stronger on tall/weedy spots. Not a night-and-day difference though.
Oh great, another self-propelled mower so it can do half the work while I sip iced tea. π
On a serious note: does anyone find the self-propel mechanism too aggressive on inclines? I don’t want it jerking forward.
You can usually manage it by starting at a lower speed and letting the mower set the pace. If it’s jerky, the drive belt or cable might need adjustment.
Haha, iced tea is mandatory. The aggressiveness varies by model β rear-wheel drive units can be more assertive on inclines. Look for a model with adjustable drive engagement so you can dial it back.
I picked the 20″ 141cc mower because storage is an issue (apartment homeowner). It starts easily and the foldable handle is a life-saver. Not for rough terrain, but perfect for flat small yards. π
Thanks for sharing, James. The compact models are great for easy storage β just watch the wheel bearings if you mow uneven ground.
50L is fine for my size yard β empties every 10-15 minutes. If you have lots of trees or shed heavy clippings, go bigger.
Do you find the 50L bag big enough? I’m debating between that and a 21″ with a larger catcher.
Nice roundup. The CVT and electric start badge on the 24-inch model clearly put it in a different class (9/10 makes sense). But I wish there were more long-term reliability stats β some PowerSmart units look great on paper but reviews mention QC issues.
Also, anyone tried to retrofit a larger catcher on the B&S models? I’m always annoyed at hopping off to empty the bag every few minutes.
If you want reduced stops, consider mulching blades and leaving clippings as long as your lawn tolerates it β less bagging required.
I’ve seen belly-mounted catchers that give more volume but they reduce turning ease. Trade-offs everywhere lol.
Good observation, Emily. We prioritized measured performance and usability in the roundup, but long-term reliability varies β we flagged models with mixed owner reports. Aftermarket catchers can work if the mounting points match, but it’s often a bit of DIY.
I swapped to a universal 3-bag system on an older Briggs mower β more capacity but adds drag and slightly changes balance. Works if you use it occasionally.
